What would the surface temperature in degrees Kelvin of the sun have to be so that the rms velocity of an oxygen atom at the surface would equal the escape velocity from the sun? The mass of the sun is 2.0x1030kg and the radius of the sun is 7.0x108m. The oxygen atom has a mass equal to 16 protons. Mass of a proton is 1.67x10-27kg.

In the Sun's core, thermonuclear reactions produce the energy which 2. eventually produces the Sun's luminosity. The Sun's core has a temperature, Tcore 1.6 x 107 K. The mass density of the core is approximately p= 1.5 x 10 kg m3. Assuming the core has the same mass fraction of hydrogen as the Sun's atmosphere (XH = 0.75), approximate the number of fusion reactions between two hydrogen nuclei (two free protons) per second. You may assume that the temperature and density are uniform throughout the core (not realistic!), which extends from the center of the sun out to about Ro/5, and that particles within the core act like a non-relativistic ideal gas (Maxwellian velocity distribution) with all reactions happening at the same relative velocity. Also assume the cross-sectional area for a proton-proton reaction is o = 2.75 x 1048 m2. %3D
